I have found unit testing to be critical in saving time. I work at a shop that has a formal “QA guy”. Releasing a newly added feature to QA without unit testing costs time and money.
I am using VS 2005’s web tests to conduct automated regression testing. It may cost me a little more time up front, but it saves the organization a lot of time in the long run.
Ironically enough, I touch on this subject in an article I just finished:
